IMPROVED INSTRUMENT FOR TREATING FISTULA, 84.0.

Specification forming part of Letters Patent NOQSLLSl, dated December 8,1863.

To all whom it may concern:

Beit known that I, EDWARD F. GARVDI, M. D., of the city and county ofNew York, and State of New York, have invented a new and usefulinstrument for medicinal and surgical purposes, to be entitled AChemical and Surgical Eradicator for Fistula, Hemorrhoids, Sac.; and Ido declare that the following is a full, clear, and exact description ofthe construction and operation of the same, referring to theaccompanyingV drawings, being a part of the specitications.

Figure l is a perspective view of the instrument with the expander e andplunger d with.- drawn as far as possible, showing the slotted pipe inits natural4 position. Fig. 2 is a view of the pipe, with the plungerand expander screwed home and the -slots expanded or opened partially.Fig. 3 is a longitudinal sectional view of the whole, showing the formof the conical tube a, with slot b, and its application to the cap c bymeans of screw c'. This cap shows the supplementary supply-chamber f andthe plunger g, which only operates in chamber j'. It also exhibits theexpander h, which passes through the plunger g and chamber f into theconical tube a. Fig. 4 is the same view, showing more fully thesuppleinentary chamber f, with plunger screwed up to the top of thechamber, resting on the lower edge of the conical tube or pipe a whenattached to the cap c. The expander his shown as turned up into theconical tube, expanding the same. Y

The nature of my invention consists in a new article of manufactureformed of caoutchouc, gutta-percha, vulcanite, wood, metal, or anymaterial of sutticient hardness and strength to be used for chemical,medicinal, and surgical purposes in the operation upon and eradicationof hemorrhoids, stula, internal or external, enabling the operator todeposit dry powdered material of any medicinal kind or quality, orunguents of any medicinal qualit-y or consistency, to the parts aiectedand for the purposes set forth.

Its operation consists in forcing any material placed in thesupplementary chamber j' by means of the plunger g into and through theconical tube a, to be deposited upon the ai'ected parts as it passesthrough the slots b. The expander h is not solid, but has orilices topermit the material to freely pass through it, the office of theexpander being to spread out and enlarge the tube' a, so as to freelyopen and expose the affected parts to the action of the remedial agent.It is intended to be employed in case of stricture am' also, and forthis purpose the instrument may be of any required length or size, andmay be used without any medicinal substance.

`The design of the instrument is to operate upon the anus and largerintestine for any disease peculiar to those parts--for itchingscrofularia, strictures, hemorrhoids, or piles, (bleeding, blind, orprotruding,) fistula, or iistulous pipes, pedical, Src.'

Having thus described my invention, what I claim, and desire to secure,is

1. The hollow conical slotted tube a, with two or more slots,substantially as and for the purposes described. y

2. The cap c, having the chamber f below tube a, substantially as andfor the purposes described.

3. The plunger g, operating in the supplementary chamber f, alsoexpander hf, both operating with or without screws, substantially as andfor the purposes described.

4. An expander, h, of equal diameter, operating ina conical tube ofunequal diameter, as and for the purposes substantially as represented.n

5. All the parts of the described instrument, singly or in combination,as and for the purposes described.
